Front

What is a translation in geometry?

Back

A translation is a transformation that moves every point of a figure the same distance in a given direction.

Front

What is the effect of translating a figure 5 units to the right?

Back

The algebraic representation is (x+5, y).

Front

How do you reflect a figure over the x-axis?

Back

The algebraic representation is (x, y) --> (x, -y).

Front

What is the difference between translation and reflection?

Back

Translation moves a figure without changing its orientation, while reflection flips a figure over a line.
